1 I This invention relates particularly to the manufacture of what are frequently called cake ornaments, such as candle holders and Christmas and birthday greetings and other forms of letters and symbols which have heretofore been made on hand operated machines.

These ornaments are formed of a plastic substance called icing deposited in a plastic condi tion onto flexible paper cards or the like and have to be carefully handled until they become hard enough to be packaged and shipped.

The present invention has as its main obJect to minimize hand operations, speed up production removed by hand but are preferably automatically placed on a conveyorsynchronized with the depositing action. Preferably the cards are handled in pairs and after the icing is deposited transferred to pallets which hold a number of pairs and are automatically passed beneath the main conveyor to an unloading position.

As these pallets are filled they are removed by the operator and placed in drying racks. As the pallets are substantiallyrigid they hold the flexible cards with the soft icing so that there is no danger of injury due to bending.

The drawings show one form of apparatus for.

carrying out the invention where the cards are handled in pairs'which is most convenient and economical. It will be understood however that the machine may be arran'ged'to handle successive single cards or successive groups of cards.

In order to avoid messing up the machine tin pressure into cylinder 9! above the piston 92 on'rod 93 on the lower end of which is mounted the plunger plate's l in container 23. The weight of piston'92, rod 93 and plunger 94 is counter balanced by the weight 95 and the cylinder has an opening with a pipe 96 to admit air to the cylinder and permit exhaust when the pressure is applied above the piston. The valves 96 and 3 6 actuated by cam 53 control the admission to the cylinder SI for raising and lowering the piston 92 and the attached plunger 514 in the container 23. If for any reason a card is missingwhen the lifter grids are raised, the finger 81 is not moved, the micro switch 83 remains open, the solenoid isnot energized and the valve 90 remains closed so that no icing is ejected.

The container 23 for the icing is closed at the bottom by the die plates 24, 24 which are detachable to facilitate interchanging die plates having the desired design. The container has side flanges 91, 9? slidably mounted on the transverse angle irons 98, 98 and held down removably by clamps 99, 99 which are hinged at I03, I63.-

The cover 23of the container is detachably held in place by clamps 99'.

The cards with the deposited articles are transferred two at a time from the main conveyor 22 to the pallets 21 which in turn are carried by the transverse conveyor 28 to the delivery table 29.

Conveyor chains 28 are carried on sprockets IilI driven from power shaft I62 (Fig. 18). The pallets 21 are supported on tracks H03 between the chains 28. The bottom pallet is moved by the cross bars I94 carried by chains 28 and the upper ones are held back by members I95.

,.The transfer mechanism has a carriage In? with rollers Hi8 guided on rails I09. This carriage is moved back and forth by a lever I I0 and link III, lever Hi3 being oscillated by link H2 and crank H3 (Fig. 18) from shaft 502.

A cross bar i2I (see Fig. 21) connects the two carriage members It? andcarries two members for gripping the edges of cards on the main conveyor 22. Each gripping member has an upper jaw I22 and a lower jaw i23 which is vertically movable and biased upwardly toward jaw I22 by spring I2 2 attached to the guide rod I25.

and moves the rod I25 downwardly to disengage the jaw I22 from the card and bring the rod I25 into position to receive the. pawl I26 in notch I32 in the rod I25. J

The transverse pallet conveyor 28 is driven. continuously and is so timed that a number of pairs of cards (in this .case four pairs) will be deposited on each pallet as itpasses under the main conveyor and to the delivery tablev from which the-pallets are removed by the operator and placed on a drying rack (not shown).

The main conveyor will be moved intermittentlyv so as to handle the cards from stage to stage of the operation but may be moved by hand for adjustment, etc., for which purpose the shaft 32 of the sprockets 32, 32 is provided with a hand wheel 32m.

the dog hits the stop I2 9 it tilts the shaft I21 and disengages the pawl I25 from the guide rod I25. Thereupon the spring 124 raises the rod with the jaw member I23 which snaps-up against the edge of a card on the main conveyor and presses it against jaw I22. The spring I 30 limits the upward movement of arm I30. The carriage is retracted and the card pulled from the conveyor- 22 and deposited on the pallet 21 on track I03.

This is accomplished by the action of the lever I30 which, as it moves to the leftlFig. 20), engages the incline I3I and is forced downwardly tracks, means forlifting cards from the tracks to the casting head, means for forcing icing from the head upon the cards beneath the head, contact fingers engaged by the cards beneath the casting head for releasing the means for forcing icing from the casting head, means for lowering the cards while the icing is being deposited and means for releasing the cards.
